Method of Determining an Access Mode of Cell in a Wireless Communication System

1. A method of determining a type of cell in a wireless communication system, the method comprising: determining a cell as a hybrid cell when a cell type indication bit is set to ‘FALSE’ but broadcast a subscriber group identity, wherein the one or more User Equipments (UEs) in a particular subscriber group or all UEs in the cell are selectively allowed to be accessed in the hybrid cell, and wherein the hybrid cell is considered by the UE as a Closed Subscriber Group (CSG) cell when the subscriber group identity of the hybrid cell belongs to an allowed Closed Subscriber Group (CSG) list of the UE.

2. The method of claim 1 , wherein the cell type indication bit is a Closed Subscriber Group (CSG) indication bit.

3. The method of claim 1 , wherein the subscriber group identity is a CSG identity.

4. The method of claim 1 , wherein the hybrid cell is considered by all other UEs as a normal cell when the subscriber group identity of the hybrid cell is not belonged to an allowed CSG list of the UE.

5. The method of claim 1 , wherein the CSG cell only allows one or more UEs in the particular subscriber group to be accessed.

6. A method of determining a type of cell in a wireless communication system, the method comprising: providing a cell type indication bit and/or a subscriber group identity to user equipment (UE) in order to determine the type of cell by the UE, wherein the type of cell is considered as a hybrid cell when the cell type indication bit is set to ‘FALSE’ but broadcast the subscriber group identity, wherein the one or more User Equipments (UEs) in the particular subscriber group or all UEs in the cell are selectively allowed to be accessed in the hybrid cell, and wherein the hybrid cell is considered by the UE as a Closed Subscriber Group (CSG) cell when the subscriber group identity of the hybrid cell belongs to an allowed CSG list of the UE.

7. The method of claim 6 , wherein the cell type indication bit is a CSG indication bit.

8. The method of claim 6 , wherein the subscriber group identity is a CSG identity.

9. The method of claim 6 , wherein the hybrid cell is considered by all other UEs as a normal cell when the subscriber group identity of the hybrid cell is not belonged to an allowed CSG list of the UE.

10. The method of claim 6 , wherein the CSG cell only allows one or more UEs in the particular subscriber group to be accessed.

11. An apparatus for determining a type of cell in a wireless communication system, the apparatus comprising: a receiving unit adapted to receive a cell type indication bit and/or a subscriber group identity; a controlling unit adapted to determine a cell as a hybrid cell when a cell type indication bit is set to ‘FALSE’ but broadcast a subscriber group identity, wherein the one or more User Equipments (UEs) in a particular subscriber group or all UEs in the cell are selectively allowed to be accessed in the hybrid cell, and wherein the hybrid cell is considered by the UE as a Closed Subscriber Group (CSG) cell when the subscriber group identity of the hybrid cell belongs to an allowed CSG list of the UE.

12. The apparatus of claim 11 , wherein the cell type indication bit is a CSG indication bit.

13. The apparatus of claim 11 , wherein the subscriber group identity is a CSG identity.

14. The apparatus of claim 11 , wherein the hybrid cell is considered by all other UEs as a normal cell when the subscriber group identity of the hybrid cell is not belonged to an allowed CSG list of the UE.

15. The apparatus of claim 11 , wherein the CSG cell only allows one or more UEs in the particular subscriber group to be accessed.
